If myClass has a constructor with a parameter of type String, select the other constructor that should be included. a. public void myClass( ) {. . .}
b. public myClass(int value ) {. . .}
c. public myClass(String str1, String str2) {. . .}
d. public myClass( ) {. . .}

d. public myClass( ) {. . .}

Explanation:

A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.

Having said these about a constructor, a few other things are worth to be noted by a constructor.

i. In Java, a constructor has the same name as the name of its class.

For example, in the given class myClass, the constructor(s) should also have the name myClass.

ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:

public void myClass(){...}

This makes option a incorrect.

iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts  of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.

This makes option d a correct option.

Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
